The anterior sacroiliac ligament is a ligament located in the human body, specifically within the pelvis. It is one of the several ligaments that make up the sacroiliac joint, which connects the sacrum to the ilium of the pelvis.

Structure

The anterior sacroiliac ligament is a broad, thin, and irregular band of fibrous tissue. It covers the anterior surface of the sacroiliac joint and connects the anterior part of the lateral aspect of the sacrum to the margin of the auricular surface of the ilium.

Function

The primary function of the anterior sacroiliac ligament is to provide stability to the sacroiliac joint. It restricts the movement of the joint, preventing excessive motion that could lead to injury.

Clinical Significance

Dysfunction or injury to the anterior sacroiliac ligament can lead to sacroiliac joint dysfunction, a common cause of lower back pain. Treatment options can include physical therapy, medication, and in severe cases, surgery.
